BACKGROUND: Pelvic fixation improves the stability of spinal instrumentation and can be used in high-grade degenerative disease, trauma, deformity, and destabilizing invasive pathologies, such as infection and tumor. Classic techniques for spinopelvic fixation include traditional iliac screws and S2-Alar-Iliac screws. We present a case series describing the distal ventral iliac pathway (DVIP) for spinopelvic fixation and discuss surgical indications and merits of this technique. We describe the use of the DVIP for spinopelvic fixation in the setting of degenerative and traumatic pathologies, compare this technique with existing approaches, and summarize literature to support this approach. METHODS: One hundred twenty-eight cases of DVIP screws were identified at 1 academic medical center, and 3 cases were chosen as representative examples for technique demonstration. RESULTS: Patient ages ranged from 19 to 81 (mean 62) years. Intraoperative and postoperative complications include 12 incidental durotomies, 3 suprafascial infections, and 2 compressive hematomas. There were 22 instances of hardware failure and 8 instances of pseudoarthrosis. Overall, 26 patients underwent revision surgery. Mean estimated blood loss, operative time, and time under fluoroscopy were 1959 mL, 386 minutes, and 3.19 minutes, respectively. CONCLUSIONS: The DVIP is both safe and effective as a treatment for patients with degenerative and traumatic lumbosacral pathology. Spinopelvic fixation provides improved soft tissue coverage and fewer hardware complications at minimum of 1 year follow up. This case series demonstrates a novel surgical technique for spinopelvic fixation in the setting of numerous spinal pathologies. LEVEL OF EVIDENCE: 4. CLINICAL RELEVANCE: This surgical technique is less technically challenging than current approaches, minimizes radiation exposure, and obviates the need for horizontal connector rods. In addition, in highly destabilizing pathologies, this technique also allows for multiple screw placement within the ilium, while maintaining the ability to connect to a single rod construct. This technique is safe, technically approachable, and broadly applicable to an array of spinopelvic pathologies.
